Compare with a Qianlong-marked tianqiuping of the same design and of similar size from the T.T. Tsui Museum of Art, sold at Christie's Hong Kong, 30 October 1995, lot 736A and again, on 27 October 2003, lot 700. Another vase of closely related size and design was sold at Sotheby's Hong Kong, 9 October 2007, lot 1522. Although a Yongzheng-marked prototype is illustrated in Sekai toji zenshu, vol. 12, Tokyo, 1956, fig. 47 and another was sold at Sotheby's Hong Kong, 27 April 2003, lot 170.
The present vase is an excellent example of the effect that could be created using the intaglio form of decoration on a monochrome porcelain vessel. The technique allows the glaze to pool into the deeper recesses, creating two contrasting tones of green and accentuating the dense archaistic design on the body and neck.
Cf. also a very fine Qianlong-marked celadon-glazed double-gourd vase decorated in the same way, included in the Exhibition of Important Chinese Ceramics from the Robert Chang Collection, Christie's London, 1993, illustrated in the Catalogue, no. 71, and a Qianlong celadon-glazed vase with comparable archaistic bands from the T. Y. Chao Private and Family Trust Collections, sold at Sotheby's Hong Kong, 8 November 1986, lot 92, sold again 27 April 2003, lot 62 and at Christie's Hong Kong, 1 November 2004, lot 875.
